- Ultra-dense deuterium D(-1) is expected to be both a superfluid and a superconductor as shown by recent theoretical research. Condensed D(-1) can be deposited on surfaces by a source which produces a stream of clusters. A magnetic field strongly influences the type of material formed. Very little of D(-1) and of the form D(1), which is strongly coupled to D(-1), exists on the magnet surface or within several mm from the magnet surface. Even the formation of D(-1) on the source emitter is strongly influenced by a magnetic field, with a critical field strength in the range 0.03-0.07 T. Higher excitation levels D(2) and D(3) dominate in a magnetic field. The excitation level D(2) is now observed for the first time. The removal of D(-1) and D(1) in strong magnetic fields is proposed to be due to a Meissner effect in long D(-1) clusters by large-orbit electron motion. The lifting of long D(-1) clusters above the magnet surface is slightly larger than expected, possibly due to the coupling to D(1). The previously reported oscillation between D(-1) and D(1) in an electric field is proposed to be due to destruction of D(-1).

- Ultra-dense protium p(l = 0) is superfluid at room temperature, as is its more often studied deuterium counterpart D(l = 0). p(l = 0) can be deposited on surfaces by a source which produces a stream of clusters. A magnetic field strongly influences the type of clusters formed. Very little of chain clusters of p(l = 0) and the closely related form p(l = 1) exists on the magnet surface or within 0.5 mm from the magnet surface. The removal of the p(l = 0) and p(l = 1) entity in strong magnetic fields is due to a Meissner effect as in the case of D(l = 0). Contrary to the case of D(l = 0), small symmetric p(l = 0) clusters formed by 3 and 4 hydrogen atoms are not left on the magnet pole face when the large chain-clusters lift in the magnetic field. Symmetric p(4)(l = 0) clusters are unlikely since four fermions cannot interact in this way. Instead, p(2) pairs are included as bosons in the chain cluster structure as observed previously.
